The emergence of the problem of holding the car is usually related to daily maintenance, and many bad habits will lead to the future of the machine holding the car, such as: engine power decline, poor oil circuit, parts wear and so on will cause the occurrence of the phenomenon of holding the car.

When you encounter the problem of holding the car, first of all, do not worry, and then check according to the actual situation. Usually start with the engine, hydraulics, circuit systems, and component connections.

Engine problem

Hydraulic pump

The car is usually caused by the engine power decline, the need to reduce the power demand of the hydraulic pump, you can adjust the pump regulator nut, after adjustment, the phenomenon of the car is usually improved. However, you will find that the action of the excavatorwill be slower and the strength will be weak, so this method treats the symptoms rather than the root cause.

engine

It can also increase the power of the engine. Many times there is a problem with the diesel pump leading to a decrease in the power of the engine, and sometimes it is accompanied by the phenomenon that the cold car is easy to start, and the hot car can not start, at this time, as long as the school oil pump and the replacement of the plunger nozzle can usually solve the problem.

supercharger

Of course, insufficient engine intake will also induce the car. Usually causes insufficient engine intake are: air filter block caused by the supercharger incomplete work; Supercharger wear; The leakage volume of exhaust branch pipe decreases. In particular, if it is necessary to replace the supercharger at any time, we must remember to drop a few drops of oil into the supercharger to achieve lubrication, and check whether the engine body connected to the small oil pipe of the supercharger is smooth.

Oil problem

Diesel quality

Many friends have mentioned that because of excessive oil impurities, resulting in filter blockage, oil circuit blockage, excessive fuel tank impurities, engine power reduction, and other problems. Usually, the quality of oil provided by private gas stations or construction sites and oil trucks will be relatively poor, with large water content and many impurities. Long-term use of such oil will not only damage the machine, but also often lead to the biggest curse of the machine. Therefore, it is recommended that we must choose regular oil supply channels, and it is recommended to use Sinopec oil, although the price is more expensive. But the quality of the oil is guaranteed.

Oil type (Diesel & Oil)

Sometimes there will be a car in winter. Due to the low external temperature and the improper selection of oil models, the diesel viscosity will increase, and the filter screen at the place where the diesel tank is connected to the engine will be blocked, and the oil supply will be poor, and eventually lead to the tank. In winter, please carefully choose the appropriate type of diesel according to the actual local conditions and temperature.

There are also organic friends of the car in the summer, the problem also appears in the oil model. There are enthusiastic friends suggest that in the high temperature season, you can use 10W-50W oil. The problem of oil may be the most easily ignored by many aircraft friends.

Identification of fake oil

Be sure to choose genuine high-quality oil, such as the current market common oil brands Mobil, bp, Shell, etc., the market is flooded with fake oil, it is recommended to go to the regular store to buy, can also be identified by price comparison reference.

Oil change cycle

Be sure to change the oil regularly, oil deterioration is also one of the causes of the car. Everything has a certain shelf life, and motor oil is no exception. Organic friends suggest that 250-300 hours to replace once, some special models may be a little longer cycle, such as Komatsu excavatorabout 500 hours to replace once. (The above data is for reference only.)

In addition, the hydraulic oil should be replaced according to the specified maintenance cycle. When using the breaker, the deterioration of the hydraulic oil is accelerated, and the replacement cycle should be shortened. After replacing hydraulic oil or hydraulic parts, pay attention to exhaust air.

Filtering problem

Filter element filter paper

Machine parts wear, oil impurities and the above mentioned diesel model problems will cause diesel filter block, suction pipe filter block, hand oil pump filter and filter block, so one by one check the filter, filter and oil connection is smooth, such as blockage, timely clean and replace.

In addition, long-term operation in the mine will produce a large amount of dust, so the air filter needs to be regularly checked and cleaned, and the compressed air is blown from the inside out when the ash of the outer filter core is long, and the air pressure can not be too large to prevent the filter core from blowing out. The inner filter cannot be cleaned. After cleaning the outer filter for 2 or 3 times, replace the new one with the inner filter at the same time.

In particular, it is recommended that the filter paper must be bought from the factory, because the filter paper of the factory is fine and the amount of impurities is large, so it is easier to block, and the replacement cycle of the filter is shorter than that of the auxiliary factory, so it is not a long-term unblocked filter element.

Component wear and aging

Some places are also the most easily ignored by many aircraft friends to check the car, such as the wear and aging of parts. Many aircraft friends will first consider whether the power needs of the engine and diesel pump are met, when you find that there is no problem, please check whether the engine cylinder liner piston is worn, whether the engine and other parts of the hydraulic system are damaged by oil leakage, if there is an anomaly must be repaired in time.

Fuel system problem

Due to the long-term use of inferior oil products caused by a large number of impurities at the bottom of the tank, it is necessary to regularly clean the tank, dredge the oil pipeline and the oil connection.

In addition, the oil-water separator is also a place that is easy to be ignored, it is necessary to regularly check whether the separation of water and oil in the oil-water separator is normal, and it is necessary to regularly open the drainage valve at the bottom to release water to avoid the excavatorholding the car due to excessive water storage.
